PRIMARY CELL.

Application filed February 10, 1914. I Serial No 817,853.

To all whom it may concern Be it known that L iunur YOUNG, a citizen of the United States of America, residing at Detroit, in the county of \Vayn'e and State of Michigan, have invented new and useful Improvementsin Primary Cells, of which thefollowing is a specification.

This invention relates to iiu provements'in primary cells" and has particular application to what are known as dry cells.

In carrying out the present invention, it is my purpose to provide a dry cell which will be comparatively small and at the same time have a relatively large capacity whereby a number of such cells may be placed within a container and connected up with one another tosupply'a heavy current.

is also my purpose to provide a primary dry cell wherein the component parts will be constructed in such manner that I after the cell has been exhausted, such cell may be connected up with a source of direct current and recharged, thereby enabling the cell to be used for a relatively long period of time.

\Vith the above and other objects in view, the invention consistsjn the construction combination and arrangement of pa rts herc inafter-set forth in and falling within the scope of the claims. f

In the accompanying drawings; Figure l is a view in elevationot a primary dry cell constructed in accordance with the present invention. Fig. 2 is a vertical central sectional view tlwrethrough. Fig. 3 is a transverse sectional view through the same. Fig. lis a fragmentary sectional view through the coil showing the parts on an enlarged scale. Fig. 5 is a top plan view of a receptacle containing a number of cells each constructed in accordance with the present invention. Fig. 6 is a horizontal sectional view therethrough showing the connections between the cells. Fig. 7 is a vertical sectional view therethrough Referring now to the drawings in detail, 1 designates my improved cell as an entirety, such cell comprising a jacket 2 constructcd of zinc or other electropositive material and circular in cross section and having a closed end 3 and an open end 4. This jacket is comparatively short in length and the inner wall at the open end thereof is cut out to form a shoulder 5 disposed a short distance inwardly of the end edge of the Patented Dec. 8, 1 9 14.

jacket, the reduced portion-being threaded as at 6. Formed on" theouter wall of the acket at the open end thereof is a lug 7 f and upstanding from the lug 7 is a. binding 9 designates a disk construct edof suitable insulating material and ha vingthe periphcry 'scre'w threaded to engage theopen end of the jacket and close, the latter.

disk is formed centrally with an opening 10 and threaded through the opening-5s a shank 11. Connected with' the inner end of the shank and preferably threaded thereon is the electro'negative element l2-of-the cell. In the present instance, this electrochlorid of magnesia dampened with water and pressed into cylindrical sticks-fond then dried and copper plated. This .electronega 70. negat ve element comprisessixteen ounces of black end of copper and, one'ounce of tive element is shorter in length tha n jacket 2 and suspended withinlthe latter centrally thereof from the'shank 11,-while threaded onto the outer end of the shank is a binding nut 13, lock nuts 14 being threaded onto the shank at the opposite sides of the disk to hold the shank against accidental movement relatively to the disk.-

Surrounding the electronegative elementwithin the jacket and'interposed between the outer surface of such element and the jacket 2 is a composition or electrolyte consisting, in this case, of caustic soda.

In practice, the shank 11 is threaded through the disk 9 and the clectronegative element connected with one end of the shank and passed into the jacket. The disk is now rotated so that the periphery thereof will threadedly engage the cut out portion of the inner wall of the jacket thereby effectively connecting the positive and negative elements and at the same time insulating such elements from each other. binding nut 1!; is now threaded onto the post 8 and bears against the adjacent portion of the disk 9 with the effect to lock the latter to the jacket. By means of the binding post 8 and nut thereon and the outer end of the shank 11 and nut 15 thereon the iespcctive conductors may be connected up with the cell so that the current generated, thereby may be consumed.

It will be noted that the shank 11 is capable of movement relatively to the disk 9 succeeding the manipulation of the lock nuts 14 to release the shank. By means of this construction, the negative electrode or element of the cell may be adjusted or moved longitudinally within the jacket or positive element so that the battery will discharge at its maximum capacity.

In the construction illustrated in Figs. 5, 6 and 7, a plurality of cells 1, seven in the present instance, are located in a container 16 and connected in series with one another and the positive' and negative terminals of the battery thus formed are connected with binding posts 17 and 18 respectively carried by the top wall of the container. The top wall of thecontainer is spaced apart an appropriate distance from the upper extremities of the cells constituting the battery so as to provide an air space, while the individual cells are wrapped with wax paper or the like in order that the cells will be effectively insulatedfrom one another. The

side wall of thecontainer at the air space therein is formed with an a .erture 19 whereby the gases may escape. y connecting the cells in series as just described and locating the same in a container, a battery is formed which is comparatively small in size and has a relatively large capacity, while when the battery has eeome exhausted the cells may be recharged by connecting the binding posts 17 and 18 with the respective conductors of a direct current circuit.

I claim:

1. A'primary dry cell comprising a jacket of electropositive material having a closed :3

end and an open end, a disk of insulating material threaded into said open end, an elcetronegative element suspended from said disk, a lug formed on said jacket at the open end thereof, a binding post extending upwardly from said lug, and a nut threaded onto said postand engaging the adjacent portion of said disk to lock the latter to the jacket.

2. A primary dry cell comprising a jacket of electropositire material having a closed end and an open end, a disk of insulating material threaded into said open end, an eleetronegative element suspended from said disk, a binding post extending upwardly from the edge of the wall at the open end of said jacket, and a nut threaded onto said post and engaging the adjacent portion of said disk to lock the latter to the jack t.

In testimony whereof I atlix my signilture in presence of two witnesses.

PHILLIP YOUNG.
